  • Secured AES encryption in wireless communication

Cable deployment is always costly for deployment and maintenance. Longer distance introduces much higher overall cost. ELA-MA is a reliable and cost effect solution to cable replacement in RS232/485 transmission. ELA-MA can achieve very good wireless performance in 2 Km distance with 90% successful transmission rate. For data transmission, ELA-MA uses LoRa 862~932 MHz to convert RS232/485 serial data among devices with LoRa wireless technology. ELA-MA is designed for easy setup and maintenance. Multi-end points can form a broadcast network, with the same frequency and encryption the end points can communicate without pairing in advance. Thus, effectively reduce the effort in deployment and maintenance.
